To all whom it may concern:

Be it known that'we, CHARLES A. CARs- CADIN and GEORGE A. WoonMAN,citizens of the United States, both residing at Chicago, inthe county ofCook and State of Illinois, have jointly invented certain new and usefulImprovements in Uncoupling Devices,'-of

which thefollowing is a specification.

' Our invention relates in general to uncoupling devices such as are inuse upon railway'cars andthe like and aims to provide a new and improvedmeans for lifting the locking pin of a coupler of any oftheordinarytypes. I, a

One of the principal objects of our invention isto provide a caruncoupling device which maybe operated from the side of the car andwhich will be so constructed that the operating rod maybe connecteddirectly to the locking pin oithe coupler, obviating therebythe use ofchains, links and 'clevises, which are at present employed inmany formsof devices of this character to connect the operating rod'to the lockingpin. The use ofuncoupling devices employing these members to connect.the operating rod to the locking pin of the coupler'hassubjected therailway companies to considerable annoyance and expense by reason-0t the'theft of these parts, which has thereby renderedthe uncoupling deviceinoperative and' r'equired thebrakeman'to'enterbetween the cars tocouple and uncouple "them great risk to thereof;

himself and in violation otthe regulations of the railway commission."Our invention description as it is better understood when.

taken in connection with the accompanying drawing illustrating preferredembodiments "Qnthe drawing, Figure 1 is a top plan view of a portion ofa "car' and coupler pro vided' an uncoupling devlce embodying ourinvention; Fig. 2 is an enlarged transverse section through the innerbracket and slide provided to connect the inner end of the operating rodto the car; Fig. 3 is a horizontal section taken substantially on theline 3-'3of Fig. 2; Fig. 4: is an enlarged-side elevation of the slide;Fig. 5 is a transverse section similar to Fig; 2 of a somewhat differentembodiment of our invention, and Fig. '6 is a similar view ofstillanother embodiment.-

Referring to the drawing, the invention comprises an operating rod 10,an outer bracket 1l,-a'n inner braclret l2 and a slide 13 carried by thebracket 12, the rod 10 pass"- ing through the bracket 11 and slide 18 aswill be later described. In the presentinstance'the operating rod isconnected directly to the locking pin of the coupler by an arm 14:extending outwardly fromthe car at right angles to the body portion ofthe rod and inserted through the eye 15 of the locking pin 16, the endofthe arm 14 being bent at 17 to prevent its disconnection from thelocking pin when the parts are inoperative position upon the car; Thebracket 11, which embraces the outer end of the operating rod,- issecured to'the car at 18 adjacent one side so that the operating arm 19at the endof'the body portion of'the'rod adjacent the side of the carmaybe-operated'without requiring the brakeman-to enter between the cars tocouple and uncouple them. The bracket 11 is of the ordinary constructionexcept that the aperture 21 is formed to per unit the operating rod *to'move pivotally about-the braclet l1"as acenter through a limited are as"the coupler head is pulled from'o'r pushed toward the car in service;The bracket-"12 consists in thepresent instance ofalbase-plate 220i"suitable formationto be secured to the car by'bolts'or other fasteningmeans 23 extending through apertures2t'in the fastening plate. Thisfastening' plate is provided with a horizontally disposed rail orbracket arm 25. In the embodimentof the invention shown in Figs. 1 to 4this'arm is of T-shaped form consisting are supporting web 26 carrying aflattened head 27; The head 27 extends throughout theiength of'the armand is'embraced by the slide "13 carrying-the operating rod. 'The slide13 is formed at its bottom with a T shaped-slot QSadapted to fit overthe bracket arm 25 and permit the slide to move longitudinally of thecar upon 'theb'racket arm.

The slide 13 is preferably provided with an upwardly extending web 29having an elongated longitudinally disposed slot 30 through whichtheoperating rod 10 is disposed, as indicated in dotted lines in Fig. 1.Adjacent the forward end of the bracket arm are provided outwardlyextending webs 31 and the width of the opening of the slot 28 ispreferably just sufficient to permit the body portion of the slide tomove easily past these websas it moves backward and forward when thecars are in service. At the rear end of the slide a pair of stops 32extend inwardly of the opening of the slot 28 to adjacent the web of thebracket arm, thus disposing them in position to engage the webs 31 ofthe bracket arm to pre- Vent excessive outward movement of the slidewith respect to the bracket 12.

In Fig. 5 a somewhat modified form of our invention is disclosed whereinthe slide which embraces the operating rod consists of a hollow casting33 provided with a pair of parallel elongated longitudinally extendingslots 34, through which the operating rod 10 is disposed. The loweredges 35 of the casting are inturned to provide a slot embracing thebracket arm 36, which in this embodiment of the invention is identicalin shape and construction with that described in connection with Figs. 1to 4:. In order that the casting may be held in proper position upon thebracket arm the sides of the casting are deflected inwardly at 37 toengage the upper surface of the bracket arm.

In Fig. 6 a third embodiment is set forth wherein the bracket arm 38 isprovided with a rounded bearing surface 39 and the slide 41 is providedwith a slot of suitable shape to engage and slide upon the surface 39.In this embodiment the lower edges 42 of the slide engage the centralsupporting web 43 of the bracket arm and the webs 44 on this arm areprovided to act as stops and terminate a substantial distance beneaththe portion of the bracket arm embraced by the slide and suitabledownwardly extending stops 45 are provided to engage the upper ends ofthese webs to prevent excessive outward movement of the slide withrespect to the bracket arm. I

An uncoupling device made in pursuance of our invention may bepositioned upon the car by inserting the end of the operating rodthrough the slot in the slide and through the aperture in the bracket11. The bracket 12, is then connected with the slide by moving the frontof the slide over the rear of the bracket arm into normal position when,after engaging the lifting arm 14; in the eye of the locking pin of thecoupler, the two brackets 11 and 12 may be secured in place. The bracket12 is preferably mounted close to the car body so that the slide can notbe moved rearwardly to disengage it from the bracket arm of thisbracket. The preferable normal relative relation between the operatingrod and the slide 13 and bracket 12 is that shown in Figs. 1 and 4. Whenthe slide is in its rearmost position, the operating rod is preferablydisposed adjacent the front end of the slot of the slide. This permitsthe operating rod to move inwardly to substantially against the car bodyand to move outwardly throughout the full length of the sliding movementbetween the slide and bracket member. It will be apparent that theproper dimensions of the parts may be readily determined to give theoperating rod the freedom of movement necessary to move with the coupleras the coupler head is pulled away from or pushed toward the car.

The parts are few in number, simple and may be cheaply constructed, andwhen connected as described, can none of them be re moved withoutdetaching one of the brackets fastened to the car.

It will be apparent that various changes may be made in the form,construction and arrangement of the parts without departing from thespirit or scope of the invention or sacrificing any of its materialadvantages, the forms hereinbefore disclosed being merely preferredembodiments thereof.
